Czekaj suffered the injury in the twenty-second minute, twisting badly in a tackle by Wallaby hooker Stephen Moore. The severity of the injury was immediately apparent, and the 21-year-old was stretchered from the field in obvious distress.
Czekaj underwent surgery in Brisbane on Sunday and has been told he cannot fly home for at least fourteen days. The Cardiff Blues wing is almost certain to miss the Rugby World Cup and could be out of rugby for up to a year.
